1 Claim.

Myinvention relates to numeral and letter forming refrigerant conduits through which the refrigerant may be circulated continuously to form a frozen letter, or numeral, or series of the same, or either of them, for advertising purposes.

The invention consists primarily of a predetermined refrigerant circuit through which a refrigerant may be circulated to form a frozen exterior upon the conduit to make the same to form letters, or numerals, or a combination of either, or both that may be used for advertising and display purposes.

The object of my invention is to develop a configuration in design and appearance through which a refrigerant may be continuously circulated to develop a frozen design upon the exterior for the purpose and object of display, or advertising.

A further object of my invention consists in developing a continuous circuit through which a refrigerant may be circulated and as circulated,

to develop a frozen delineation that may be used for display, and advertising purposes.

A still further object of the invention is the vprovision of a display sign of this character wherein each of the characters is mounted individually within the circuit but each being in open communication with its adjoining character so that a continuous circuit is thereby formed and at the same time rendering each of said characters readily accessible and removable in the event of necessity of repair.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claim, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

In the drawings:

Fig. 1 is a diagrammatical layout of a refrigerant circuit through which a refrigerant may be pumped, or circulated for the developing of the word Eat, as a frozen sign.

- of the mechanism illustrated in Fig. 2. The

same being taken on line 33, of Fig. 2, looking in the direction indicated.

Fig. 4 is a plan view, partially in section, of the letter T as illustrated in the word Eat in Fig. 1.

Fig. 5 is a front view of a refrigerant circulating system connected to my sign and showing diagrammatically the closed circuit created thereby, and the brine containing cabinet partially in section.

Fig. 6 is a front view of my invention in a frosted condition.

Like reference characters refer to like parts throughout the several views.

The refrigerant, the source of which is not here shown enters the conduit at 1, and. is circulated in a continuous path to develop the 3 letters of the word Eat. The refrigerant entering the circuit at 1 and is circulated through the upright portion of the letter E, through the vertical portion of the letter 2, and through the upper horizontal portion of the letter as illustrated at 3. The refrigerant then passes through the central portion 4, of the conduit and outward I refrigerant then passes through the base 15, and

through the conductor 16, that is disposed within the staff of the letter T. The refrigerant passes from the vertical portion 16, into the head 17. A partition 18 is disposed within the letter T to require the refrigerant to flow through the horizontal portion 19, of the head of the letter T, and thence downward through the staff portion 20, and into the base 21, where the refrigerant may then be circulated back to the source of supply. The refrigerant is circulated through the 7" base, as herein outlined. All portions of the letter will appear to be of the same and desired size without passing, or returning upon itself as is now the general custom. Letters and numerals,

or a combination of either or both of the same may be thus delineated and outlined to produce the greatest display and advertising value, for the letters, or numerals, or combinations of the same to be delineated.

In Fig. 5 is shown my invention connected to a brine circulating system and forming a closed circuit therewith. Conduit 22 leads into and connects with the cooling coils 23 disposed within the container 24 holds has disposed therein the brine 25. The container is disposed upon the base 26 which also holds thereon the prime mover 27. The prime mover is connected to a circulating pump that is associated with the coil system and expedites the movement of the refrigerant therein. Conduit 28 leads from the other end of the cooling coil and connects with the conduits that form the sign to be frosted.

It will be noted that the hollow base portion of each of the characters is internally threaded at both of its ends and provided at one of said ends with a union coupling as shown in Fig. 4 so that all of said letters may be united and firmly held in open communication with each other.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claim which follows.

What I claim is:

In a device of the class described, the combination with a refrigerating system, of a plurality of characters of hollow tubular formation adapted to be joined together in open communication to form a continuous conduit through which a refrigerant may be circulated to form a froste coating upon the exterior thereof, each of said characters having a plurality of bafiie plates dis posed therein, and supplemental tubular members' extending through said bafile plates for directing the refrigerant through a predetermined path throughout the entire interior of the character, means formed in each of said characters for joining one With the other in open communication, said means including an individual section of tubing in open communication with each individual character, said individual tubing being internally threaded at both of its ends to threadedly receive a hollow union coupling, and each of said individual tubings being formed with a partition substantially midway its length.
